Japan\'s Nikkei ended higher on Monday morning, after yen-selling intervention by the government boosted export-linked shares. The benchmark 225-issue Nikkei Stock Average was in negative territory in early trading, with export-related issues weighed by the yen\'s continued appreciation against the dollar. But the Nikkei rose following yen-selling action by monetary authorities, ending the morning session up 45.80 points, or 0.51 percent, from Friday to 9,096.27. It temporarily rose as high as 9,152.39, its highest intraday mark since Aug. 8. The broader Topix index of all First Section issues on the Tokyo Stock Exchange was up 3.65 points, or 0.47 percent, to 775. 08.
